Violent/aggressive confrontation? Sure. =3

But when it comes down to things actually getting out of hand with fighting and whatnot (like serious fighting, not just a few punches or something), that's when it should stop. If you're questioning for your life (or his no matter how much you hate him), it's probably time to stop. D8

Otherwise, kick his ass. =3 And then tell me how it goes. XD

I'm pretty sure Jesus would kick his ass at this point.

You know the situation better than we do. Do what you think is right. If it's bad enough that you wanna kick his ass...go for it. Just make sure you've got enough money in the bank to make bail before you do it in case you get arrested for it.
